Let's take a look at two flavors that are fancy enough to be in their own bottles:
Tabasco first: I thought maybe, just maybe, there was an outside chance that this might simply be cinnamon with a little spice added to it, but nope: you get the full-on, mashed-red-pepper-based, spicy aftertaste experience. Which is gross. Even if you like Tabasco sauce, it's just not fun to, um, chew it.
The champagne bottle was...different. It certainly tasted like champagne, so it was at least in the realm of something that a jellybean should taste like. But it also had a weird aftertaste, almost like a fake alcoholic taste, as if somehow we're going to be fooled into thinking that we can get drunk off of this stuff. (Sadly, you can't, although that won't stop me from trying later.)
You can probably skip the Tabasco one unless you're the sort of person who receives plush bottles of Tabasco sauce for your birthday. The champagne one actually isn't bad, although i can't imagine eating more than a few on occasion, so a small bottle you can share is about right.
I didn't have the nerve to mix the two at once. Feel free to let me know how that goes.
